Abstract

MéTODO PARA OPERAR EM SISTEMA DE REVESTIMENTO DURANTE PERFURAçãO Pelo menos uma parte de um poço submarino é perfurada com técnicas de revestimento durante a perfuração. Um ombro de assentamento é formado dentro de uma coluna externa de um revestimento. A coluna externa de revestimento é fixa em um alojamento de cabeça de poço externo acima do ombro de assentamento e abaixo para dentro do furo de poço. Um suspensor de revestimento é fixado em uma coluna interna de revestimento e abaixado através da coluna externa de revestimento para dentro do furo de poço. Uma broca de perfuração na extremidade inferior da coluna interna de revestimento é girada para aprofundar o poço. A coluna de revestimento interna se move para baixo à medida que o poço está sendo aprofundado até assentar o suspensor de revestimento no ombro de assentamento. Um elemento de conexão é fixado em um alojamento de cabeça de poço interno e abaixado para engate de vedação com o suspensor de revestimento. O alojamento de cabeça de poço interno aterra no alojamento de cabeça de poço externo.METHOD FOR OPERATING IN COATING SYSTEM DURING DRILLING At least part of an underwater well is drilled with coating techniques during drilling. A seating shoulder is formed within an outer column of a covering. The outer casing column is fixed in an outer wellhead housing above the seating shoulder and below into the wellbore. A casing hanger is fixed to an inner casing column and lowered through the outer casing column into the wellbore. A drill bit at the lower end of the inner casing column is rotated to deepen the well. The inner casing column moves downward as the well is deepened until the casing hanger is seated on the seating shoulder. A connecting element is fixed to an inner well head housing and lowered for sealing engagement with the liner hanger. The inner wellhead housing lands on the outer wellhead housing.
